Power Savings doesn't turn monitor off on NUC8i5INH

[Gerry Paradis]

On previous versions of Ubuntu, after 5 minutes, my monitor would turn off as per settings. Since I reinstalled fresh 21.10, this is not happening. Screen becomes black and stays powered on.

This sounds like bug 1929650, which has been generalised in https://gitlab.gnome.org/GNOME/mutter/-/issues/1991

[Daniel van Vugt (vanvugt)]

Does it work if you log into 'Ubuntu on Xorg'?

[Gerry Paradis (volksdude)]

Same thing with Ubuntu on Xorg

[Daniel van Vugt (vanvugt)]

If the bug is the same for Xorg and Wayland then that suggests you need a kernel fix (the 'linux' source package). Can you please try some slightly older kernels and see which was the last working version for you?

I run Ubuntu Budgie 21.10. Since two days before turning off display after idle went well (DPMS mode).

Since yesterday turning off display doesn't work anymore. The display goes black for a second but then it comes back again. However, the screen is frozen (no repainting) as long as I use the desktop, e.g. keyboard, mouse movements.

I guess that this is related to a recent update of libmutter. There has been an update (see /var/log/apt/history.log):

System is also an Intel NUC (NUC8I3) but I don't think that it is limited to this setup.

I had a simular problem earlier with Ubuntu 21.04 and Kodi media center (see also https://github.com/xbmc/xbmc/issues/19479). I have closed this issue a few days before since I though it was finally solved. This time there is no output when I watch the events by using xev.

The workaround setting MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0in /etc/environment mentioned in https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1929650 doesn't help.

Edit 2021-11-18 21-25

After further analysis I found out that the root cause isn't any update of mutter. The root cause seems to be my bluetooth mouse. For some reason it prevents the system to go into idle mode altough it hasn't been moved.

Therefore my problem und analysis weren't related to the issue that is reported here.

Sorry for any confusion.
